TUBE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 228,162, dated June 1,1880,

Application led March 23, 1880. (Model.)

To all 'whom it may concern:

My invention relates to paper-bag machiny ery, and more particularly tothat portion of said machinery devoted to the formation of the tube fromwhich the bag is subsequently formed; and it consists in forming aplicated tube by means of passing the same over two separate formers,during which operation the paper is held to the edge of the formers bymeans of guides.

In the drawings, Figure 1 is a plan view of a machine embodying myinvention. Fig. 2 is a longitudinal vertical sectional view of the same.Fig. 3 is a sectional view of the tube after it has passed the iirstformer. Fig. 4 is the same View of the tube after it has passed thesecond former and is completed with the exception of being united bypaste.

In the said drawings, A represents aframe adapted to contain theoperative parts of my device. B represents aroll of paper. C representsa guide-roll, situated above the roll of paper and near the terminus ofthe iirst former.

D represents the first former. This former consists of a plain surfaceadapted to rest upon the body of the machine, and of a widthcorresponding to that of the width of the tube required, and ofsufficient length to complete the formation of the first fold of thetube. It is constructed in two parts, the tirst lying parallel andresting upon the body of the machine, upon the top of the paper, itssecond part consistingl of an angular portion that terminates at or nearthe guide-roll O. The whole may be held in position in any suitablemanner. As shown in the drawings, I connect it to the cross-piece of themachine, from which it is suspended.

per upon the outer edges of the former, and

also make the center fold ot' the plication.

G is a second guide-roll, situated beyond the terminus of the rstformer, and over which the paper passes before it reaches, the secondformer, H. This second former, H, is constructed substantially in thesame lnanner as the rst former, D. It also has its guides I and K, thathold the paper upon the former H, by means of which the last fold ismarked or creased.

L and M are feed-rolls, between lwhich the tube, after being formed,passes, and by means of which the paper is drawn from the roll B overthe formers and through the guides.

The operation of my device is as follows: A roll of paper of anysuitable length and of a width required to form the sized bag desired isplaced in position, as shown in Fig. 2 at B. The end of the paper isdrawn over the guide-roll C, passed under the former D, the guides E andF are turned in place, which causes the fold in Fig. 3 to be made, andat the same time there is made, by thepressure of the ends ofthe formerupon the advancing web of paper, the fold b, which is the central foldof the plication. Being thus formed, the paper is carried over thesecond guideroll,G, under the second former, H, where it passes underthe former having its rst or lower folds completed. The last fold, c, asshown in Fig. 4, is made by the guides I and Kpressing the paper uponthe edge of the former. From thence it passes between the feed-rolls Land M, from whence it is taken to the mechanism by which the bottomfolds of the bag are made and the bag severed from the tube `following.

Paste may be applied at any step in the process, either as the paper istaken from the roll B, or at any other convenient point before itreaches the feed-rolls L and M. I prefer to apply it at or near theguide-roll G.

I have found by experiment that it is immaterial the position my formersD and H occupy-that is, whether the longer portion of the forme-rs restsupon the bed of the machine or whether the formers, as shown in thedrawings, are inverted with the angle portion upward, the result will besubstantially the Same.

What I claim isl. In a tube-machine, the combination., with one formerand guides, which form the rst and second side folds in a bellows-sidedtube, of a second former, located in a different plane from the iirstformer and made independent thereof', and lateral guides which form thethird side folds, substantially as set forth.

2. In a tube-machine, the combination, with one former and guides, whichform the first and second side folds in a bellows-sided tube, of asecond former made independent of the first former and located inadifferent plane therefrom, guides which form the third side folds, and asupporting device located between the two formers, and on which the webhas lateral bearing as it passes from the first to zo the second former,substantially as set forth.

3. In a tube-machine, the combination, with one former and guides, whichform the first and second side folds in a bellows-sided tube, of asecond former made independent of the z 5 first former and located in aplane below the saine, guides which form the third side folds, and aroller located between the two formers, substantially as set forth.

In testimony whereof I have signed my 3o name to this specification inthe presence of two subscribing witnesses.

DANIEL APPEL.
